ABSTRACT
The Takakura Composting Method has experienced decreasing degree of the
effectiveness in organic matter degradation due to several factors. The objective of the research
is to know the effect of adding yeast and sugar into Takakura Inoculum. There were two control
and three variation include control A (8 kg new inoculum), control B ( 8 kg used inoculum),
Variation C (8 kg used inoculum : 75 gr sugar), Variation D (8 kg used inoculum : 20 gr yeast),
Variation E (8 kg used inoculum : 20 gr yeast : 45 gr sugar). Yeast is a consortium of
microorganism and sugar is a good nutrition resource for microorganism.
The measurement result showed that the adding sugar and yeast didnot affect the
degradation of organic matter process and humification process. Temperature Control A was in
thermophilic phase and Variation B, C, D, E used old inoculum in mesophilic phase in
degradation process. The temperature got to be lower until room temperatur if it didnot be
added by rice. The pH of Compost was about neutral measurement 6,4 up to 7,4. Twenty days
later, physical characteristics of compost was shown. They are blacky brown in color, loose and
soil smelling. Laboratory test result showed that Carbondioxside, Nitrogen, Potassium, Phospor,
Water Level, Physical Condition were qualified for compost standart according to SNI no 197030-2004. However, these minerals content wasn’t enough compared to other organic compost
standards of PT. Pusri and Agriculture Departement. Takakura compost is good for ornamental
plant, pot plant, fruit with the correct mixing procedure.
Key Word: Inoculum, Yeast, Sugar
